Core–shell nano-latex blending method to prepare multi-shape memory polymers

18-Jul-2017 | Hongze Li; Yingwu Luo; Xiang Gao, Soft Matter, 2017

Multi-shape memory polymers were prepared by blending a series of styrene (St)-block-(styrene-random-meth acrylate (MA))-block-styrene triblock copolymer nano-latexes. These latexes synthesized using a reversible addition-fragmentation chain transfer (RAFT) emulsion polymerization method have a ...

Fluorine containing self‐crosslinking acrylic latexes with reduced flammability and their application as polymer binders for heterogeneous cation‐exchange membranes

14-Jul-2017 | Jana Machotova, Eliska Stranska, Jiri Skornok, Lucie Zarybnicka, Klara Melanova, Jozef Rychly, Adela Ruckerova, Journal of Applied Polymer Science, 2017

ABSTRACT In this study, self‐crosslinking core–shell latexes comprising copolymerized perfluorethyl groups and a novel flame retardant based on phosphazene derivative were prepared by the semi‐continuous non‐seeded emulsion polymerization of 2,2,2‐trifluorethyl methacrylate, methyl ...

Study of the surfactant role in latex–aerogel systems by scanning transmission electron microscopy on aqueous suspensions

12-Jul-2017 | A. PERRET, G. FORAY, K. MASENELLI‐VARLOT, E. MAIRE, B. YRIEIX, Journal of Microscopy, 2017

Summary For insulation applications, boards thinner than 2 cm are under design with specific thermal conductivities lower than 15 mWm−1K−1. This requires binding slightly hydrophobic aerogels which are highly nanoporous granular materials. To reach this step and ensure insulation board ...

Improved mechanical properties and abrasion resistance of styrene butadiene rubber/butadiene–styrene–vinyl pyridine rubber/clay nanocomposites with strong interfacial interaction

03-Jul-2017 | Xiaohui Wu, Yonglai Lu, Yiqing Wang, Liqun Zhang, Polymer Composites, 2017

Given the advantages of the latex compounding method, clay was nanodispersed into a styrene butadiene rubber (SBR) matrix, and butadiene–styrene–vinyl pyridine rubber (VPR) latex was introduced to in situ‐modified clay to support strong interfacial interaction between clay layers and SBR matrix. ...

Staggered Linear Assembly of Spherical-Cap Colloids

27-Jun-2017 | Yogesh Shelke; Manigandan Sabapathy; Ethayaraja Mani, Langmuir, 2017

Linear assembly of colloidal particles is of fundamental interest in visualizing polymer dynamics and living organisms. We have developed a fluid–fluid interface-based method to synthesize spherical-cap polymeric latex particles. These particles are shown to spontaneously self-assemble in zigzag ...

Gyrification-Inspired Highly Convoluted Graphene Oxide Patterns for Ultralarge Deforming Actuators

09-Jun-2017 | Yinlong Tan; Zengyong Chu; Zhenhua Jiang; Tianjiao Hu; Gongyi Li; Jia Song, ACS Nano, 2017

Gyrification in the human brain is driven by the compressive stress induced by the tangential expansion of the cortical layer, while similar topographies can also be induced by the tangential shrinkage of the spherical substrate. Herein we introduce a simple three-dimensional (3D) shrinking ...

Heteroaggregation of oppositely charged particles in the presence of multivalent ions

06-Jun-2017 | Tianchi Cao; Takuya Sugimoto; Istvan Szilagyi; Gregor Trefalt; Michal Borkovec, Physical Chemistry Chemical Physics, 2017

Time-resolved dynamic light scattering is used to measure absolute heteroaggregation rate coefficients and the corresponding stability ratios for heteroaggregation between amidine and sulfate latex particles. These measurements are complemented by the respective quantities for the homoaggregation ...

Measurement of the Density of Engineered Silver Nanoparticles Using Centrifugal FFF-TEM and Single Particle ICP-MS

17-May-2017 | Soheyl Tadjiki; Manuel David Montaño; Shoeleh Assemi; Angela Barber; James Ranville; Ronald Beckett, Analytical Chemistry, 2017

A methodology has been developed to measure nanoparticle mass and density, by combining centrifugal field-flow fractionation (CeFFF; more commonly called sedimentation FFF or SdFFF) and transmission electron microscopy (TEM). Particle effective mass obtained from CeFFF retention data and particle ...

Core–shell and gradient morphology polymer particles analyzed by X‐ray photoelectron spectroscopy: Effect of monomer feed order

16-May-2017 | Florent Jasinski, Victoria L. Teo, Rhiannon P. Kuchel, Monique Mballa Mballa, Stuart C. Thickett, Richard H. G. Brin ..., Journal of Polymer Science Part A: Polymer Chemistry, 2017

ABSTRACT The synthesis of composite latex particles possessing core–shell and gradient morphologies, respectively, using seeded starve‐fed semibatch emulsion polymerization of styrene (St) and methyl methacrylate (MMA) is presented. The focus is on the effect of the monomer feed order on the ...

Polysiloxane/polyacrylate composite latexes with balanced mechanical property and breathability: Effect of core/shell mass ratio

15-May-2017 | Jie Shen, Jian‐wu Sun, Yang Hu, Cheng‐you Kan, Journal of Applied Polymer Science, 2017

ABSTRACT Polysiloxane/polyacrylate (PSi/PA) core/shell latexes are fabricated, and the particle morphology, the film structure, as well as the properties of the latex films are investigated by comparing with blend latexes, and the relationship between structure and property is proposed. ...
